graphics view framework.</p>
<p>When a <a href="qgraphicsview.html">QGraphicsView</a> receives a
<a href="qmouseevent.html">QMouseEvent</a>, it translates it to a
QGraphicsSceneMouseEvent. The event is then forwarded to the
<a href="qgraphicsscene.html">QGraphicsScene</a> associated with
the view. If the event is not handled by the scene, the view may
use it, e.g., for the <a href="qgraphicsview.html#DragMode-enum">DragMode</a>.</p>
<p>In addition to containing the item, scene, and screen
coordinates of the event (as <a href="qgraphicsscenemouseevent.html#pos">pos</a>(), <a href="qgraphicsscenemouseevent.html#scenePos">scenePos</a>(), and
<a href="qgraphicsscenemouseevent.html#screenPos">screenPos</a>()),
mouse events also contain the coordinates of the previous mouse
event received by the view. These can be retrieved with <a href="qgraphicsscenemouseevent.html#lastPos">lastPos</a>(), <a href="qgraphicsscenemouseevent.html#lastScreenPos">lastScreenPos</a>(),
and <a href="qgraphicsscenemouseevent.html#lastScenePos">lastScenePos</a>().</p>
